[3.x] Copy Blade files on installation

[jessarcher]

This PR updates Jetstream so that it copies the Livewire components on installation to make it more like Breeze, and more like the Vue stack.

I've placed them in resources/views/components instead of resources/views/vendor/jetstream/components where they are currently published, to give the user a better sense of ownership over the components, and to leverage Laravel's anonymous components.

I've also removed the jet- prefix from the components.

Finally, I've also made it copy the email views on installation for both stacks so there's no resources that aren't copied. I named the directory resources/views/emails to match the suggested directory from the Laravel docs (here and here)

I've marked this as 3.x because I believe it is a breaking change to remove the ability for existing Jetstream users to publish the views. We could potentially still offer the publishing, but I think we'd need to maintain the jet- prefix to keep it compatible with their existing views.

@jessarcher thanks - will we need any docs changes here?

@taylorotwell indeed! I have created a draft PR at https://github.com/laravel/jetstream-docs/pull/70 to add docs for 3.x
